Not really a wierd question - you will probably find better answers using the search function than you will asking this in a thread about the overall game meta-strategy.
For this year, our team is dicifering upon either a x drive or a mechanum drive.
Here are the pros and cons we have found of each,
Mechanum:
Pros:
Easy to build
Faster??
Cons:
Not as good at turning
Takes up lots of space
X drive:
Pros:
Good at turning (large aspect of starstruck)
Small amount of space taken
Cons:
Harder to build
Slower??
What are you guys doing, what is your opinion on this?
If you had to pick between the 2 I would agree with @steven1233f and say go with the x-drive. If you are going v5 then I’d recommend going for a regular holonomic (no mechanum) drive since it takes less motors.
Mecanum drives and X-drives work exactly the same in principle. However, Vex’s mecanum wheels have much higher friction (and lower efficiency) than omni wheels at 45°. This is the main problem with them.
Mechanums generally require a wider than normal chassis but with an x drive the front is angled inwards so you could go further into the corner
In starstruck and toss up, we had a tank drive that uses two traction wheels in the back and two omni wheels in the front (helps with turning). This is my favorite chassis design since it is reliable and fast.
However, I think an x-drive will be the best bet for this year.
First of all, this video does not demonstrate a difference in stall torque. Each motor can deliver the same amount of force, the stall torque is only determined by the radius of the wheel. A larger radius, the less torque the wheels will be able to deliver. Since all of the wheels in the video are 4 inches in diameter, or close enough to it, the torque applied from the motors is the same. Instead, the video demonstrates traction, or the ability for the wheels to transfer the torque of the motor…
